HaploReg v3

HaploReg v3

Broad Institute Homepage MIT

HaploReg is a tool for exploring annotations of the noncoding genome at variants on haplotype blocks, such as candidate regulatory SNPs at disease-associated loci. Using LD information from the 1000 Genomes Project, linked SNPs and small indels can be visualized along with their predicted chromatin state, their sequence conservation across mammals, and their effect on regulatory motifs. HaploReg is designed for researchers developing mechanistic hypotheses of the impact of non-coding variants on clinical phenotypes and normal variation.

Update 2014.02.14: Version 3 now includes an improved motif library and final reference epigenomes the Roadmap, including predicted causal enhancer motif instances. The GWAS library has also been updated and revamped by aggregating across traits and pruning. Version 2 is available here.

Build Query

Use one of the three methods below to enter a set of variants. If an r² threshold is specified (see the Set Options tab), results for each variant will be shown in a separate table along with other variants in LD. If r² is set to NA, only queried variants will be shown, together in one table.

Query (comma-delimited list of rsIDs OR a single region as chrN:start-end):
or, upload a text file (one refSNP ID per line):
or, select a GWAS:
